EYEGLASSES.

Specification of Letters Patent.

Patented Aug. 1, 1916.

Application filed March 27, 1916. Serial No. 87,067.

To all whom it may concern Be it known that I, GUSTAV A. BADER, a citizen of the United States, and resident of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Eyeglasses, of which the following is aspecificatign.

The present invention relates to eyeglasses and more particularly to the type used for protecting or shielding the eyes against flying particles, an object of the invention being to provide a construction in which the head-attaching devices, which hold the frame or mounting before the eyes, are foldably connected to the frame and at the same time are interlocked with the frame at points removed from the pivots of the head-attaching devices, so that the entire strain of the head-attaohing devices is not imposed on the pivots.

Another object of the invention is to provide a construction in which the pull on the head-attaching devices, when in use, tends to maintain the devices in interlocking connection with the frame to prevent swinging of the head-attaching devices on their pivots.

Still another object of the inventionis to provide members at opposite sides of the main frame foldably mounted on said frame and having temples carried thereby and connected with devices which interlock with the main frame at points removed from the pivots of the members.

A further object of the invention is to provide eyeglasses in which the lenses are readily removed so that the user may insert others quickly when the originallenses have become broken. H

To these and other ends, the invention consists of certain parts and combinations of parts all of which will be hereinafterdescribed, the novel features being pointed out in the appended claims.

In the drawings: Figure 1 is a rear view of eyeglasses constructed in accordance with this invention; Fig. 2 is a top-view of the glasses; Fig. 3 is an enlarged front view; Fig. 4- is a section on the line aw, Fig. 1; F 5 is a section on the line Z)-b, Fig. 4; Fig. 6 is a view illustrating an eye-shield shifted partially to show the manner of disconnecting the devices which interlock with the frame; Fig. 7 is a section on the line cc, Fig. 5; Fig. 8 is a view similar to Fig.

I, of a modification; Fig. 9 is a section on the line 0ZZ, Fig. 8; Fig. 10 is an enlarged view from the inner side of the eyeglasses showing the devices for detachably securing the lenses to their seats; Fig. 11 is a section on the line ec, Fig. 10; Fig. 12 is a section on the line ff, Fig. 10; Fig. 13 is a perspective view of one ofthe lenssecuring devices; Fig. 14 is a perspective view of the device which holds the lens-securing devices against movement; and Fig. 15 is a detail view from the inner side of the eyeglasses showing the manner of releasing the lens locking devices.

In the illustrated embodiments there is provided a frame or mounting preferably formed of a single piece of sheet material cut toprovide two openings surrounded by lens seats 1 on which the lenses 2 rest, the term lens being used to cover any transparent or translucent medium. About each seat, a flange is formed, this flange overhanging the seat at 3 throughout the greater portion thereof and on the outer side of the frame, while at 4 the flange is bent at right angles to the seat so that, while it prevents the lateral movement of the lens in the plane of the latter, it will permit the lens to be removed from its seat from beneath the overhanging portion 3. This flange 4 also serves as a wide nose bearing portion as will be hereinafter shown.

That portion of the eyeglass frame or mounting between the lens seats acts as the bridging portion for bridging the nose, and is reduced with relation to the lens-seats so that the nose may fit between the lenses. This bridging portion has its lower edge turned outwardly at 5 to provide a flange which forms a continuation of the lens securing flange portion 4-, and serves to provide a wide bearing surface for engaging the nose. The upper portion of the bridging portion is rolled into tubular form at 6, so as to provide a surface which may bear with comfort against the forehead of the user, this rolled portion forming a continuation of the lens-securing flanged D01- tions 3. Between the rolled or tubular portions 6 and the flanged portion 5, the bridging portion of the frame is pressed outwardly at 7 to provide, on the inner faces ofthe bridging portion, a chamber or pocket 8 which serves as a passageway for the circulation of air between the two eyes. The

inner Walls of this chamber also serve to confine the lenses 2 to their seat and, to this end, are curved to conform to the curvature of the seats for the lenses. The chamber may also be utilized by mounting devices for detachably securing or looking the lenses in place.

For the latter purpose, the end Walls of the chamber 8 are slotted at 9, and. through these slots two lens-securing or locking devices 10 are projected from the chamber 8. These lens-locking devices in this instance are in the form of plates having deflected portions 11 which overhang the bezels of the lenses 2 The main portions of these plates lie in the pocket 8 and are adapted to swing on the walls of the slots 9 as fulcrums to carry the portions 11 toward and from the lenses. The locking devices 10 are so formed that they may be passed through the slots 9 by turning them about their portions 12 as pivots after which lugs 13 on the locking devices are bent up to prevent such locking devices from accidentally becoming detached from the frame. A latch 1 1 preferably of the shape of a crescent is pivotally mounted at 15 and serves to secure both looking devices against movement, while at the same time the latch may be turned in either direction to free either one of the locking devices, as shown in Fig. 15. iVhen securing both locking devices, the latch lies in the position shown in Fig. 10, and a projection 16 thereon enters between the locking devices 10 so that the latch is held against rotation.

Any suitable head-attaching devices may be employed but in this instance, temples 16 engage behind-the ears of the wearer and are pivotally secured at 17 to links 18, which, in turn, are pivotally connected at 19 to any suitable part on the frame or mounting. The purpose of providing these links is to permit the main frame to adapt itself to the face of the wearer without producing any action in the temples. It is well known that it is now required to bend temples so that they will properly engage the ears of a user, or so that the frame or mounting may lie in proper position on the face of the user and the temples will properly engage the ears.

To the end of foldably connecting the temples with the frame, the pivot 19 between eachlink 18 and the frame may be arranged on a device 10 in the form of a slide. This slide is mounted on a pivoted frame or part 21, the latter being of skeleton formation and having a guide thereon for the slide, said guide being formed by inwardly-turned flanges 22 overhanging the slide 20. The frames 21 are curved to conform to the curvature of the lens'and are pivoted at 23 on ears 24, said ears extending laterally from extensions 25 Which proceed from the inner edge of the lens seats 1 and overlap the main frame or mounting, the pivots being located at points removed from the ends of the main frame or mounting and at diametrically opposite sides of the lens seats. The slides 20 may carry hooks 26 or other devices which are adapted to interlock with the ends of the frames in order that the strain of the temples will be removed from the pivots 23 and placed directly upon the main frame or mounting. These hooks disengage with the main frame or mounting when the parts 21- are swung on their pivots 23, this being due to the fact that the hooks are movably mounted on the parts 21 by means of the 1 slides 20. When the hooks 26 are interlocked with the main frame or mounting, a projection 27 on the part 21 enters into a depression or pocket 28 on the slide 20 and holds the parts 21 against accidental movement to folded positions. A rib 29 may be formed on the slide 20 for the purpose of strengthening the latter transversely. If desired, a curved shield 30 may also be pivoted at 23, so as to surround the frame 21 and prevent the entrance of particles into the eyes at the ends of the frame or mounting. A deflected portion 32 may be provided in each slide to limit the movement of the latter.

In Figs. 8 and 9 there has been shown an embodiment in which the slide 20 is mounted directly upon the shield 30", thus eliminating the swinging frame 21. The slide 20 is guided on the inner side of the shield by straps 31, and the shield is provided with a projection 27, which engages with the depression 2S to lock the slide 20", so that the hook 26 is held interlocked with the main frame. This construction is not so desirable as that shown in the other embodiment, as it does not permit the device to be made either with or without the eye-shields, it being apparent that in the embodiment shown in the other figures the eye-shields 30 may be eliminated when it is not desired to protect the eyes against the entrance of particles at the ends of the main frame.

To remove either one of the lenses, it is merely necessary to turn the latch 1-21- until the desired locking device 10 is freed from the latch, after which such latch may be swung to carry the portion 11 out of engagement with the bezel of the lens. The lens is then pressed slightly at a point adjacent the bridging portion to carry it from beneath the flange 3. This arrangement permits the user of the device to fit new lenses in place when the old ones have become broken.

In folding the head-attaching devices, the guards or shields are swung inwardly by pressure near their swinging ends. During the first part of such swinging movement, the slide 20 pivots on the main frame,

i as

as shown in Fig. 6, but does not swing away from the main frame. After a time the hook 26 disengages with the main frame so that the slide with the hook may swing with the shield, thus permitting the latter to fold upon the rear face of the main frame. hen the hook 26 is interlocked with the main frame, the shield is held against accidental movement by the projections 27 entering the depressions 28, but this holding means readily gives or yields upon pressure on the shield to fold it inwardly.

Eyeglasses constructed in accordance with this invention permit the users to readily substitute other lenses'for broken ones. The

head-attaching devices are connected to the main frame in such a manner as to fold inwardly, while, at the same time, the strain on the head-attaching devices is removed from the pivots of said devices and placed upon the main frame at points removed from such pivots through the means of de vices which interlock directly with the main frame. These interlocking devices automatically disconnect from the main frame upon the inward folding of the head-attaching devices, yet so long as the strain is imposed upon the head-attaching devices, when the latter is in use, the interlocking devices are effectively held in connection with the main frame.
